# Description
A plate using one filament no longer reserves or draws a prime tower in
the plater just because multiple filament slots are configured. The
shared footprint estimate gated "no tower" on the purge volume being
zero, but on non-Bambu printers with the shipped defaults that volume
comes from the SEMM flush matrix, which reads every configured slot and
stays nonzero even when only one filament is used — so the preview
showed a tower the print could never contain. The estimate now decides
from the filament count alone, with wrapping detection and smooth
timelapse staying the only reasons a single-filament plate keeps a
tower, matching `Print::has_wipe_tower()`. The gate also moved above the
flush-volume scan so the lone-filament path no longer pays for it.
No change to slicing output — toolpath generation already omitted the
tower for a single used filament; this removes the phantom preview,
placement reservation, and validation footprint.

Added a shipped-defaults single-filament case to
`tests/libslic3r/test_wipe_tower_estimate.cpp`: it estimates a 5.04
mm-deep tower before the fix and zero depth after. `[WipeTowerEstimate]`
and the fff_print `[WipeTower]` suites pass.

The no-tower case was gated on there being no purge volume, but the SEMM flush matrix reads every configured slot and is nonzero even when only one filament is used, so the plater preview drew a tower the print would never contain.
Four files overlapped, and each resolution favours upstream where the two sides
had done the same work:
WipeTower's M104/M109 tool qualifier. Both sides bounds-checked the physical
extruder map lookup; upstream omits the T qualifier when the map cannot answer,
where this branch fell back to the logical index and so named a carriage that may
not be the one printing. Upstream's behaviour is what this branch documents
elsewhere, so its version is taken and the local helper is dropped.
get_extruders' mixed-slot switch. Upstream added the same concept to the CLI
overload as expand_mixed_slots, so the GUI overloads' parameter is renamed to
match rather than carrying two names for one idea.
GLCanvas3D's sequential-clearance branch gains upstream's
update_compacted_wipe_tower_clearance for the by-layer case.
The printer_agent re-sync in TabPrinter::reload_config was upstream's and their
preset-undo fix removed it, so it goes; the IMEX modes grid re-sync beside it
stays, since it spans three options and is not a Field.

imex_wipe_tower_hull() open-coded "does this plate print a tower?" as one
filament and no forcing reason. normalize_fdm_2, which is what actually
clears enable_prime_tower before slicing, has a second arm the copy omitted,
and reads the mixed-filament flag project-wide where the copy read the
plate. Two cases went wrong in opposite directions.
A ByObject plate with several objects prints no tower and the scene draws
none, yet the copy validated one and could refuse the slice with "the prime
tower overlaps an area reserved for IDEX/IQEX parallel printing" - with
nothing on screen to move.
A plate using one plain slot while some other slot in the project is a blend
does print a tower, because normalize_fdm_2 keeps it for any mixed filament
in the project, and the copy skipped validation entirely, so the tower could
be placed in a carriage zone and sliced.
prime_tower_is_printed() in libslic3r states the rule once, and both the
gate and a test use it. The counts are the ones normalize_fdm_2 is handed:
filament slots as authored, so a mixed slot counts once, and distinct
objects rather than instances. filament_is_mixed is a project option, so it
is passed in rather than read from the print preset.
The test drives every combination the rule looks at and compares the verdict
against normalize_fdm_2 itself, so the two cannot drift again without
failing.

With single_extruder_multi_material and purge_in_prime_tower, the flush
matrix replaces the prime volume and its average is non-zero for one
filament, so the estimate reports a tower. normalize_fdm_2 clears the tower
for that same plate, so none is printed: the estimate answers how big a
tower is, never whether there is one, and a caller reading a non-zero depth
as "a tower is printed" reserves space for, or blocks on, a phantom. The
test asserts that disagreement directly.
Type1 is the exception in the same case, because it decides from its
per-filament purge list and a lone filament is never changed to. The scene
reads the same estimate either way. Type2 is the default for every non-Bambu
printer, and so for every IDEX/IQEX one.

nozzle_temperature is variant-expanded, so its length is columns rather than
filament slots. On the dynamic-nozzle path that makes it longer than the
slot count, and an out-of-slot index reached get_filament_config_index() and
came back as filament 0 - the clamp the bounds-checking was meant to remove.
Bound by the slot count instead; on the ordinary path the two are equal and
nothing changes. The is_extruder_used write gains the matching lower-bound
guard.
IMEXHelpers.hpp now states both halves of the rule its call sites follow.
Bound anything derived from the extruder map against the filament slot count
before using it as a filament id, not against the option about to be read.
And a miss is -1, which is a correct tool qualifier but matches no physical
head, so it cannot serve as a skip-the-primary sentinel: which head prints a
filament is answered by the filament and the map, never by a mode role,
since a primary-mode print may use any or all tools, one at a time.
The consequence is recorded there rather than left implicit. The two skip
sites skip nothing for a slot past the end of the map, so a plate with more
slots than nozzles double-writes the primary's pressure advance. It is
narrow and unreported, and a guard there would be a smaller change than
naming a head.
The header also records that RepRapFirmware sends an unqualified pressure
advance as M572 D0, naming drive 0 absolutely rather than the active tool.

The parallel printing options shipped to testers as is_ixex and ixex_*,
became is_imex and imex_* when the feature stopped being called iXex, and
the two clearance keys were renamed once more to say what they measure:
nozzle to carriage edge on the collision side, not the carriage's full
width. Nothing translated any of it, so loading an existing printer profile
dropped every one of these values - the keys are unknown and cleared.
is_ixex is the one that matters most, because without it the others migrate
into a feature that stays switched off, leaving settings that look
configured and do nothing.
Per-plate mode is persisted twice and only one path went through
handle_legacy. Plate metadata in a 3MF is matched by exact attribute name
and written with set_key_value, so a project saved between the per-plate
mode landing and the rename loaded every plate back on Primary and sliced
single-carriage with no warning. The loader now accepts the old attribute
name.
ixex_primary_col and ixex_primary_row are dropped rather than mapped: the
primary is a role inside the mode's active-tools string now, not a grid
coordinate, and they were never in an option list, so no saved file carries
them.
The test drives the full era-1 key list and asserts the enum values rather
than non-nullness, since a forward-compatible substitution would otherwise
hide a failed deserialize behind a default. handle_legacy had no test before
this.

Two range-for loops bound const std::string& to braced lists of string
literals, so each iteration constructed a temporary to bind to. GCC 16
reports it as -Wrange-loop-construct, which upstream's blanket -Werror turns
into a build failure; clang does not report it at all. Spell the
initializers the way the loop above them already does.

Review findings on the preceding commit, plus one defect it should have
caught.
- The IDEX/IQEX pressure-advance loop fed resolve_filament_for_head()'s
result straight into enable_pressure_advance and pressure_advance. That
result is bounded by physical_extruder_map, which holds one entry per
NOZZLE, while both options are indexed per filament SLOT. On a printer
with more nozzles than the project has filaments the two spaces diverge
and get_at() clamped the overflow onto filament 0, emitting its pressure
advance on a secondary carriage. The second-layer temperature loop bounds the
same lookup, but against nozzle_temperature, which is variant-expanded and so
is not the slot count either -- it is not the precedent it looks like.
IMEXHelpers.hpp states the rule
once, and a test pins the contract that makes the bound necessary:
resolve_filament_for_head() answers in nozzle space, so a non-negative
result is not by itself safe to use as a filament id.
- The header claimed every caller renders a -1 tool qualifier as "emit
none". RepRapFirmware substitutes the historical D0 instead, deliberately
and with its own comment in GCodeWriter. Say so, rather than leaving a
contract a future author would code against.
- A cross-reference pointed at a hard-coded line number that the preceding
commit had itself shifted by nine lines. Name the function instead.
- The multi-color rejection reasons reach the user through Print::validate()
as raw English, while the returns on either side of them use L(). Wrap
them and register IMEXHelpers.cpp for extraction. They also still said
"IMEX", the internal name, so they move to IDEX/IQEX with the rest of the
user-facing strings rather than shipping the internal one to translators.
- Trim the preceding commit's comments. One block explained the same
clamping hazard six times; the canonical explanation now lives in
IMEXHelpers.hpp and the call sites point at it. The mode grid carried
twelve lines of commentary and no code, most of it archaeology already in
the commit message, and one claim about the modes editor that was not
true. The ArrangeJob threading note stays: it documents an invariant that
cannot be recovered from the code.

Review findings on the IDEX/IQEX parallel printing code, all in paths the
feature owns.
- physical_extruder_map lookups used ConfigOptionVector::get_at(), which
clamps an out-of-range index to values.front() rather than reporting a
miss. The map holds one entry per nozzle while filament ids index slots,
and nothing caps the slot count at the nozzle count, so a project authored
with more filaments than the printer has extruders silently addressed the
primary's head: pressure advance pinned to the wrong carriage, and
skip-primary loops suppressing whichever head sat at pem[0]. Bounds-check
at all four sites and treat the miss as "no mapping" (-1). Covered by a new
imex_pem_tool_for test; the header note now warns against get_at here.
- IMEXFilamentPickerPopover leaked a top-level window per ghost click:
wxPopupTransientWindow::Dismiss() only hides, and never reaches OnDismiss().
Destroy from an OnDismiss() override and dismiss the picker through
DismissAndNotify(), which is the path a successful pick takes.
- ArrangeJob read PartPlate's IMEX zone cache from the worker thread, where
a cache miss rebuilds GLModel members with no GL context current while the
GUI thread may be painting them. Snapshot the zones in prepare(), on the
main thread, already converted to plate-local coordinates.
- The mode grid anchored its row window to the Primary's gantry row. A window
as tall as the grid can only start at row 0, so this drew tiles for tools
that do not exist and hid real ones. Render the whole grid instead; a
Primary outside it is a data problem the zone layout already reports.
- Build the mode tooltip from one format string rather than two catalog
fragments concatenated around a runtime value, so translators can move the
mode name within the sentence, and register IMEXModesCtrl.cpp for string
extraction.

---------
Co-authored-by: Rodrigo Faselli <162915171+RF47@users.noreply.github.com>
* Run every profile maintenance job from one tool
orca_id_tool.py becomes orca_profile_tool.py, and orca_extra_profile_check.py
and orca_filament_lib.py fold into it as subcommands: check, generate-id, fix,
trim, update-index and update-snapshot. The three scripts already overlapped --
the checker imported half of its rules from the id tool, which in turn kept a
copy-pasted set of output helpers to avoid the resulting import cycle -- while
disagreeing on how a vendor is enumerated, how a JSON file is read and what the
exit code means. One file settles all three.
check, normalize, trim and update-index reproduce their predecessors exactly; normalize and
update-index were diffed byte-for-byte against the old scripts over a copy of
the whole tree. Deliberate changes: the compatible-printers check no longer
switches itself off when --check-materials is passed, an error exits 1 rather
than -1, update-index honours --profile-type and reports a profile it cannot
place instead of dropping it from the index, fix and update-index gained
--dry-run, trim keeps an unindexed file some surviving profile still inherits
from, and vendors are enumerated as directories with an index -- which is why
blacklist.json, a data file that an unscoped index rebuild once wrote four empty
list sections into, loses them here and will not collect them again. The dead
rename_filament_system() helper is gone.
The suite under scripts/tests now covers the maintenance commands too, and CI
runs it; nothing there ran in CI before. No shipped profile data changes apart
from those four keys.
* update vendor index files with "python3 ./scripts/orca_profile_tool.py update-index" and "python3 ./scripts/orca_profile_tool.py normalize"
* CLI: --ground-face-* / --lay-flat / --center-on-bed orientation primitives
Adds the CLI counterparts to the GUI's lay-flat / face-pick gizmos.
Scripted / CI / AI pipelines can now set orientation without rendering
a wxWidgets frame; today the only way is a GUI round-trip.
New CLI actions (all operate in the mesh-local frame so they compose
with prior --rotate-* / --orient flags):
--ground-largest-face 1 Auto-detect the largest planar-face
or --lay-flat 1 cluster (area-weighted), rotate so its
normal points -Z. Covers "this part has
one obvious flat side" cases.
--ground-face-normal NX,NY,NZ Pick the face whose mesh-local
normal best matches the given
vector; ground it. e.g.
`--ground-face-normal 1,0,0`
stands a part on its +X side.
--ground-face-point X,Y,Z Find the triangle containing the
given mesh-local point; ground its
face. Disambiguates when several
faces share a normal (largest
containing triangle wins).
--center-on-bed 1 Translate so the XY bounding-box
centroid lands at the bed center
(derived from printable_area).
New file `src/slic3r/Utils/MeshOrient.{hpp,cpp}`:
- collect_triangles_object / compute_face_clusters — quantize
per-triangle normals (0.001, ~0.06°) and area-weighted-average
within clusters. Same clustering logic used by lay-flat.
- apply_ground_rotation — same math as Selection::flattening_rotate
in the GUI (Selection.cpp:1432): world-space quaternion from the
transformed normal to -Z, applied as offset * new_rot * old_no_offset
on every instance of every object, then a per-instance Z-lift so the
grounded face lands at exactly 0 (avoids "No layers were detected"
from FP-error z≈-1e-9).
- ground_face_point uses a top-N cluster search + point-in-triangle
test in local space; largest-area triangle wins on ambiguity.
Rationale: without these, any CLI pipeline that needs a specific
face on the bed must either encode custom rotation math per part or
break out of the pipeline into the GUI. Both are bad for
reproducibility. The --ground-face-* triple + the largest-face
auto-mode cover essentially every orientation intent expressible
in a slicing wizard.
Scope:
- `src/slic3r/Utils/MeshOrient.{hpp,cpp}` — new, ~420 lines
- `src/slic3r/CMakeLists.txt` — 2-line registration
- `src/libslic3r/PrintConfig.cpp` — 5 new CLIMiscConfigDef entries
- `src/OrcaSlicer.cpp` — 58-line handler block + 1 include
No behaviour change when the flags are absent.
(cherry picked from commit c45a9795e1)
* CLI grounding: choose among the Lay on Face planes, per object
Addresses review:
- Move the geometry of GLGizmoFlatten::update_planes() into
libslic3r/LayOnFace and use it from the gizmo and the CLI, so the
--ground-* options pick convex-hull faces per object and instance,
with part transformations (--rotate-x/y) applied.
- Drop --center-on-bed, the --lay-flat alias and MeshOrient; make
--ground-largest-face a coBool.
- Parse --ground-face-normal and --ground-face-point strictly. A point
that only some objects contain grounds those and leaves the others.
- Fold in --inspect-mesh from #14603, reporting the same planes.
- Tests in tests/libslic3r/test_lay_on_face.cpp: bounding boxes before
and after, rotate then ground, two objects, and a ribbed part whose
parallel inner faces outsum its base.
* CLI --inspect-mesh, --ground-face-*: reject missing input and empty values
- Without an input file or --load-assemble-list, --inspect-mesh printed
nothing and exited 0. Reject it up front with CLI_INVALID_PARAMS.
- An explicit empty --ground-face-normal or --ground-face-point was
silently ignored. Only options given on the command line reach the
transforms loop, so an empty value now fails the strict parse like any
other malformed value.
* fix: guard H2C per-filament array reads against short config arrays
The H2C tool-ordering, wipe-tower, and g-code export paths index per-filament
config arrays by filament/tool id. A config with fewer entries than the filament
count (partial or legacy projects, minimal test configs) makes these reads run
past the end of the vector: silent under a normal STL, but UB that aborts under
the flatpak build's bounds-checked STL (_GLIBCXX_ASSERTIONS).
Route the reads through the existing clamping accessors (get_at,
get_filament_category, is_in_same_extruder) and add a small clamp helper for
filament_change_length. The guards are no-ops when the arrays are sized to the
filament count, so correctly specified configs are unaffected.
* fix: size the grouping context's filament_info to the filament count
build_filament_group_context built model_info.filament_info by walking
filament_type, so a config whose filament_type is shorter than the filament
count produced a short vector. FilamentGroup indexes filament_info by filament
id, so clamping the individual reads only moved the out-of-bounds access
downstream. Loop to filament_nums and read all three fields through get_at,
and drop filament_ids entries past the filament count, since the grouping code
pairs filament_ids and filament_info by position.
Adds a regression test with four filaments and one-entry filament_type /
filament_is_support. Without the fix it throws bad_alloc from copying a garbage
std::string read past the end.
* fix: guard the carousel nozzle-change length reads too
The carousel branch added in b90ac13d86/b0dddb4648 reads
m_filaments_change_length by tool id without a bounds check, the same
pattern this branch already routed through filament_change_length_at
a few lines above in both plan_toolchange and plan_tower_new.
* fix: guard WipeTower per-filament array reads against short config arrays
The BambuStudio WipeTower sync reintroduced raw per-filament array
indexing that reads out of bounds when a config leaves an array shorter
than the filament count: m_physical_extruder_map in format_line_M104/M109
(indexed even when empty), and m_filament_categories in get_wall_skip_points
and get_wall_filament_for_all_layer. Silent on a normal STL, a hard abort
under the bounds-checked STL the Flatpak build uses.
Bounds-check the physical extruder map before indexing (omitting the T
token, as the existing -1 path already does), and route the two raw
m_filament_categories reads through the clamping get_filament_category()
accessor the surrounding code already uses. No change for correctly-sized
configs.

Since #15438, every CLI run that loads a system preset spends about a
second per preset file re-parsing that vendor's entire profile tree. A
slice with a machine, process and filament preset got roughly 2.5 s
slower, and a four-filament slice roughly 4 s slower. This PR loads each
vendor tree once per run instead. Resolved presets and G-code are
unchanged.
The GUI never takes this path, and no release contains #15438, so the
regression only affects CLI runs on current dev and nightly builds. That
includes print farms, slicing services and plugins that call
`orca-slicer --slice`, and CI suites.
## Changes
### Why it was slow
`PresetBundle::resolve_preset_config` resolves a system preset through
its vendor manifest by loading the whole OrcaFilamentLibrary bundle and
the whole vendor tree from JSON, then picking the one preset out. The
CLI did that separately for every `--load-settings` and
`--load-filaments` file, on a fresh `PresetBundle` each time. With BBL
presets, a machine + process + filament run opened `BBL.json` three
times and read BBL's 2,879 profile files and the library's 512 three
times over.
### Load each vendor tree once
- `PresetBundle` keeps every vendor bundle its manifest path loads,
keyed by source root, vendor and substitution rule, and reuses them for
later resolutions on the same bundle.
- OrcaFilamentLibrary is cached the same way, so vendors under one root
share a single library load and the library's own presets resolve from
that same instance. A vendor bundle only reads from its base while
loading, so sharing it is safe.
- A failed or throwing load is not kept, so error reporting is
unchanged.
- The key includes the source root, so presets from two different
profile roots still resolve separately.
- The CLI resolves every system preset through one `PresetBundle` for
the whole run, instead of creating one per file.
The resolved configurations still come from the same canonical vendor
loader, so what a preset resolves to does not change. Only the CLI calls
`resolve_preset_config`, so a long-lived GUI bundle cannot end up
holding profile trees that later change on disk.

-->
- New test "Manifest-backed resolution reuses the vendor tree it already
loaded" in `tests/libslic3r/test_preset_bundle_loading.cpp`. It resolves
one preset, changes the parent profile on disk, then resolves a sibling.
The same bundle returns the value it already loaded, and a fresh bundle
picks up the change.
- New test "Manifest-backed resolution shares the library between
vendors under one root". It resolves through one vendor, changes a
library profile on disk, then resolves through a second vendor and a
library preset on the same bundle. Both return the value already loaded,
and a fresh bundle picks up the change.
- All `[Preset][Bundle]` tests pass (87 test cases, 1,069 assertions),
including the existing manifest-backed resolution cases for source-root
scoping, malformed vendor loads, missing parents and type mismatches.
- G-code of the three-preset slice is identical before and after, header
lines excluded.
- The external CLI regression suite passes. Two cases report as
unexpectedly passing because #15639 fixed their bug. They pass the same
way on this PR's base without the change.
- A GUI-vs-CLI parity run over 10 fixtures shows no new differences.
- Builds clean on Linux (Release, with tests).

Testing](https://www.orcaslicer.com/wiki/how_to_download_pr_artifacts)
The manifest resolver loaded OrcaFilamentLibrary once per vendor it
resolved through, so a run that mixes vendors parsed the library tree
again for each of them. The library is now cached like any other vendor
tree, keyed on its root and substitution rule, and doubles as the base
every vendor under that root loads against. A vendor bundle only reads
from its base while loading, so sharing the instance is safe.
The cache key carries the substitution rule as its enum, and the lookup
lambdas take a const bundle since they only read.
`--export-settings` already writes the merged config as JSON at the
right point in the CLI flow. Passing `-` now writes that same document
to stdout, so scripts can inspect the effective config without a temp
file. This replaces #14605.
- `ConfigBase::save_to_json` gains a stream overload. The file overload
serializes through it before opening the file, so the output format is
unchanged, and a config that cannot be serialized (invalid UTF-8) now
leaves the existing file untouched instead of truncating it.
- On stdout, invalid UTF-8 in string values is written as U+FFFD instead
of ending the process with an uncaught `type_error`. Files keep the
strict behaviour.
- To keep stdout pure JSON, `-` is rejected up front (stderr message,
`CLI_INVALID_PARAMS`, shell status 254) when combined with an action or
transform that can write to stdout or does real work: `--info`,
`--help`, `--orient`, slicing and exporting. Options that do nothing
without a slice (`--uptodate`, `--min-save`, `--pipe`, ...) are still
accepted.
- The one unconditional stdout write on a success path, "skip locked
instance" during arrange, now goes to the log.
- Every other value, including the default `output.json`, behaves as
before.
Tests in `tests/libslic3r/test_config.cpp`: the stream output equals the
file output and keeps the tab-indented format; invalid UTF-8 throws on
the strict path and is replaced when asked; a failed save leaves the
previous file intact.
Opening a model with a relative path, for example `orca-slicer ./some.3mf`,
failed with "Loading of a model file failed." and "The file does not contain
any geometry data.", while the same file opened by an absolute path or by
drag and drop worked.
GUI_App::init_app_config() changes the working directory to <data_dir>/log,
and it runs from the GUI_App constructor because the app config is needed
early for instance checking. The input files are opened much later, in
post_init(), so a path still relative at that point resolved against the log
directory instead of the directory OrcaSlicer was started from, and the 3MF
reader failed to open it.
Resolve the input paths in CLI::setup(), which runs before GUI_App is
constructed and therefore before the working directory moves. Absolute paths
are returned unchanged, so the forms that open today are unaffected, and
custom open protocol URLs are passed through since post_init() hands those to
the downloader rather than the file loader.
The working directory change is left alone. It was added in #3248 so the TUTK
logs land in the data directory instead of the working directory (#3209).
--export-settings already writes the merged config as JSON at the right
point in the CLI flow. Passing - writes the same document to stdout.
- ConfigBase::save_to_json gains a stream overload. The file overload
serializes through it before opening the file, so the format is
unchanged and a config that cannot be serialized leaves an existing
file untouched instead of truncating it.
- On stdout, invalid UTF-8 in string values is written as U+FFFD instead
of ending the process with an uncaught type_error; files keep the
strict behaviour.
- - is rejected up front when combined with an action or transform that
can write to stdout or does real work, so stdout carries only the
JSON.
- The unconditional "skip locked instance" stdout write during arrange
now goes to the log.
- Tests in tests/libslic3r/test_config.cpp.
Cover the two cache paths the first test left open: a vendor tree that fails to load is retried on the next resolution instead of being served from the cache, and a type-probed filament resolved through resolve_preset_config_type reuses the OrcaFilamentLibrary base already loaded for a sibling.
Resolving a system preset through its vendor manifest loaded the whole vendor tree and the filament library from JSON, and the CLI did that separately for every --load-settings and --load-filaments file. A run with machine, process and filament presets parsed BBL's 2,879 profile files and the library's 512 three times over, about a second each.
Keep the library and vendor bundles loaded by the manifest path on the PresetBundle that resolved them, keyed by source root, vendor and substitution rule, and have the CLI resolve every system preset through one bundle for the whole run. A failed load is not kept, so errors are reported as before.
On a cube slice with X1C machine, process and PLA presets: 2.42 s -> 0.93 s, BBL.json opened once instead of three times, identical G-code.
update_values_to_printer_extruders_for_multiple_filaments picks each
filament's value from the flattened (filament x variant) columns of every
per-filament variant option. When a column index fell past the end of the
option's values, it skipped that filament and left the zero the output
vector was created with.
The GUI always hands this function full columns, but the CLI does not:
- a CLI override of a single value, such as --nozzle-temperature=211 on a
four-filament project, came out as 211,0,0,0, so three filaments would
print at 0 C;
- loading fewer filament presets than the project has filaments left the
remaining filaments' columns missing, so filament_cooling_before_tower
came out as 10,10,0,0 and filament_ramming_volumetric_speed as -1,-1,0,0.
An out-of-range column now keeps the option's first value, the fallback
get_at() and the sibling gather step already use. The seven per-type copies
of the loop are replaced by that same gather_option_values helper, moved
above the function; it now takes its caller's name for its log lines. An
empty option, which has no first value, is given one registered default per
filament first; it used to be replaced with zeros.
On a partial load a filament whose preset was not loaded takes the first
filament's value rather than its own preset's, which the CLI does not load;
for the options seen in practice those agree.
* build: clear 2 warnings - cast the NSTextField the class check already proved
mainframe_text_field is NSTextField* and was assigned a bare NSView*, which
Clang reports as -Wincompatible-pointer-types. Both assignments sit inside
if ([viewObject class] == [NSTextField self]), so the runtime type is already
guaranteed, and the line above the second one casts the same variable the same
way to call setTextColor. macOS only, since nothing else compiles this file.
* build: clear 6 warning categories from the clang-cl inventory
-Wmissing-braces (9). Aggregates whose first member is itself an aggregate.
GUID's fourth member is BYTE[8], so the trailing eight bytes take their own
braces. The others were reaching for zero-initialization with {0} and say {}
now. bbs_3mf's backup Task ends in an anonymous union, which needs braces of
its own; those braces initialize the union's first member rather than the one
named at the call site, so the RemoveBackup site says so in a comment.
-Wmacro-redefined (11). SendMultiMachinePage.hpp defines five names that
Preferences.hpp, PresetBundleDialog.hpp, ExportPresetBundleDialog.hpp and
TroubleshootDialog.hpp also define with different values, so the value in
force depended on include order. All nine of this file's DESIGN_ macros take
the SEND_ prefix it already uses for its own macros, values unchanged, so a
DESIGN_ name added elsewhere later cannot collide with it again. They read as
one page-local palette, a 900 to 400 gray ramp plus sizes, so the four with
no current readers stay: dropping them would leave gaps in a named scale. test_marchingsquares.cpp defines NOMINMAX,
which libslic3r already passes as a PUBLIC compile definition, so it takes
the #ifndef guard the other suites use.
-Wbraced-scalar-init (3). Two PushStyleVar calls resolve to the float
overload, so the braces were initializing a scalar. ConfigOptionFloatsNullable
already takes an initializer_list, so the inner braces did the same thing.
-Wmicrosoft-goto (2). Both gotos in copy_file_gui jump forward over the
initialization of size, dwRead and dwWrite, which only MSVC accepts. Those
declarations move up to join the others at the top of the function.
-Wunused-private-field (3). Every use of ColourPicker's m_clrData and
m_picker_widget is behind !defined(__linux__), so on Linux they are written
and never read; the members now carry the same guard. ParamsPanel's
m_size_move is read nowhere. Tab has its own, which is the one Tab.cpp uses.
-Wnonportable-include-path (2). BaseException.h asked for "stackwalker.h"
and the file on disk is StackWalker.h.
fix: report the real error when a Windows G-code export fails
copy_file built its failure message as "Error: " + errCode. Adding a DWORD
to a string literal is pointer arithmetic, not concatenation, so the pointer
lands errCode bytes into an 8-byte literal and runs past its end for any code
above 7. std::string then calls strlen on it and throws length_error, and the
catch(...) in BackgroundSlicingProcess::finalize_gcode replaces the diagnosis
with "Unknown error occurred during exporting G-code."
Every code a user is likely to hit is past the end: write-protected media is
19, no media 21, a full disk 112, and a destination held open by another
program 32. Codes 1 to 7 stay inside the literal and produce a truncated
message instead. So the "Maybe the SD card is write locked?" text has not
been reachable on Windows since this path was added in #2923.
Now that it is reachable, that guess only fits removable media, so it is
conditional on m_export_path_on_removable_media. The existing string is
untouched and keeps its 23 translations; the fixed-drive case adds one string.
The preview brim, the placement margin and the pre-generation validation
warning each decided on their own whether the tower has a Type2 cone
base, reading the wall type and cone angle three different ways. The
preview's read cast the preset's enum to ConfigOptionEnum<T>, which a
preset-shaped config never holds, so the cone base was never previewed.
estimate_wipe_tower_first_layer_outline now answers that question once,
beside the footprint estimate, from the config and the resolved planner;
all three sites take the outline from it. The libslic3r case reads the
outline off a preset-shaped config, where the old cast came back empty.
Smooth timelapse no longer charges a prime volume it does not purge. A
tower printed with no tool change is exactly the idle depth: the
stability minimum for Type2, the wrapping detection depth for Type1.
Charging a full prime_volume on top made the previewed and arranged
tower deeper than the one that is printed.
The Type2 half of "a tool change reserves a tower whatever the purge
volumes resolve to" arrives with the base commit; here it only has to
survive the planner split, since Type1 already reserves per filament.
The wipe tower filament only joins the tool ordering when there is a
tower to join, which is the has_wipe_tower() half of the guard
Print::extruders applies.
The shared estimate reserved every tower with one volume-per-purge rule
and the stability floor. Both planners do more: WipeTower (Type1) wipes
each filament's own prime volume in whole lines, one block per
adhesiveness category sized by its worst layer, rams the leaving
filament at every nozzle change, and squares a rib tower from the
planned depth; WipeTower2 (Type2) spaces its lines by
wipe_tower_extra_spacing, not the Type1-only infill gap, and its extra
flow cancels out of the depth. Both extend the ribs rather than the body
below the stability minimum, size every layer including a thinner first
one, and lay the brim in whole loops, WipeTower reporting half a spacing
of line width on top.
All of that now lives in estimate_wipe_tower_footprint, fed the planner
(resolve_wipe_tower_type mirrors Print::wipe_tower_type and the CLI's
Bambu Lab detection) and the filament ids rather than a count. Print
passes its own tool set; the PartPlate adapter derives the plate's ids
from the passed config and treats an explicit count as a floor, so the
CLI's count-only callers size per filament too. The placement clamp also
reserves a Type2 cone's base bulge, which the body box does not cover.
The planner-mirroring helpers sit beside the planners in WipeTower and
WipeTower2 so the two stay in sync; the libslic3r cases pin them to
footprints measured from generated G-code.
A raft is not a reason to reserve a tower. Print::apply runs
normalize_fdm_2, which clears enable_prime_tower for a plate that purges
one filament unless smooth timelapse or wrapping detection is on, so a
single-filament plate with a raft prints no tower at all and the estimate
was reserving bed area for one. Drop the input; need_wipe_tower is now
exactly the two exceptions normalize_fdm_2 honours, named there so the
next reason added has to be checked against it.
The GUI preview and the validation containment check each re-derived
"is a tower printed here" from the filament count instead of reading the
estimate, so both missed the towers printed with no tool change to purge
for. They now take the answer from the footprint, which is the drift this
shared estimate exists to remove. A tower that is not printed estimates to
zero, so its hull is degenerate and every check on it passes trivially -
the containment check needs no gate of its own.
WipeTowerData::width was written only by the pre-generation estimate and
left at zero for the whole post-generation life of the Print, while its
neighbour depth held the real value. Set it from the generator in both
branches.
The plate's height scan transformed every model part's full mesh per
instance on each scene reload, discarding all but the z extent. The
cached convex hull has the same z extent.
A plate loaded from a sliced .gcode.3mf holds no objects and its filaments
live in slice_filaments_info; the config-taking get_extruders overload
returned an empty list for it, which sized the tower for a placeholder two
filaments. It now answers the way the wx overload does, without reaching
the plater.
Also drop estimate_wipe_tower_size, which has no callers.
